Your help is much appreciated! A scientist is studying the population growth rates of two different types of bacteria under the same laboratory conditions. The number of bacterial cells of type A is represented by the equation shown, where P represents the number of bacterial cells at the end of x hours. P = 2x + 19 The number of bacterial cells of type B is represented by the equation shown, where Q represents the number of bacterial cells at the end of x hours. Q = 3x + 18 At the end of Number___(answer here)hour(s), there will be the same number of bacterial cells of type A and type B.
